...contains two separated tungsten electrodes, a little pool of mercury, a tungsten filament. When the electric switch is turned, current heats the filament to incandescence. The heat vaporizes the mercury. The mercury vapor diffuses between the electrodes and permits the current to jump across as a brilliant mercury arc. The combined light of arc, electrodes and filament appears much whiter than Mazda "daylight" bulbs. It produces 40 times as much humanly beneficial ultraviolet radiation as does the midday midsummer sun of equal intensity...
Operator Vivian scooped up the loose ends of wire, held them tightly together in one hand. An arc burned his hand. To close the arc he squeezed harder. The harder he squeezed, the more current leaked into his arm, made it jerk crazily. Had he not been standing on a cork-insulated floor, had he not kept clear of a well-grounded duct a few inches from his foot, the 220-volt current would have killed...
...strips sewn in a membrane of goat-skin-flew so hard that it hurt bare hands. The players took to wearing gloves, then invented and strapped to their throwing wrists a long shallow wicker basket (called cesta). hooked like a giant's fingernail. The length of the throwing arc added speed to the little ball, heightened the game's excitement, sent it back across the ocean with other Spanish improvements to Mexico City, where it ranks next to bullfighting; to Havana, where another season of it is now in full stride...
...importance of the single personal command, the importance of time." He was the biggest big executive of his day, a man who spent his life bringing order on a large scale out of colossal chaos. Louis' father, Charles VII, had been that weak-kneed Dauphin whom Joan of Arc crowned. Charles turned out better as a king than he had been as a Dauphin; but when his impatient son Louis (he led two rebellions against his father) came to the throne, at 38, he found France still disunited, Paris disloyal, the English threatening, and such powerful nobles...
...building marches Rear-Admiral William Adger Moffett, chief of the Navy's bureau of aeronautics. With him are President Litchfield, Designer Arnstein, Commander Jerome Clark Hunsaker, who Drobably will head the Pacific Zeppelin Transport Co. (see col. 3). They mount a platform above the arc of the master ring. President Litchfield explains the ceremonies to spectators and microphones. Dr. Arnstein hands Rear-Admiral Moffett the gold rivet and a silver-plated hand riveting machine, which looks like a dentist's forceps. Admiral Moffett places the rivet in the proper hole, squeezes it with his little machine. The band...
